How often do I need to change the VAZ jets and how can I determine the malfunction?

The fuel injector is the most important detail in the design of each car. Without it, not a single modern passenger car, including cars of the Volga Automobile Plant of the tenth family, can do without it. Nozzles (VAZ 2110-2114) are used to spray fuel at the expense of high pressure, which is several atmospheres. In this article, we will learn how to determine the malfunction of this part, through how much you need to replace and clean them.

Service life

Now, probably, every Russian motorist knows what "quality" fuel he pours into the tank. That gasoline, which is sold at gas stations at 30 rubles per liter, can not be called pure. In any case, it will contain some percentage of sulfur and impurities, but how much it will be in gasoline, it already depends on the integrity of the company. As practice shows, fuel injectors (VAZ 2112-2114) need thorough cleaning after 20-30 thousand kilometers of run. Therefore, they should be cleaned at least once a year.

What signals the malfunction of the injectors?

Of course, it is not necessary to wait until the counter is added to the arrow of another 20 or 30 thousand kilometers (possibly, this spare part will live even at 40 thousand), since the exact period of their operation is always different. And in order to notice the malfunction in time, you need to know certain signs, according to which the car behaves strangely. They include the following factors:

• The engine suddenly stalls at idle.
• The average fuel consumption increases by 10-30 percent.
• The machine can not give out the same power that it developed before.
• The speed of the car then increases, then decreases.
• The exhausts became more polluted.

If you notice at least one of these signs, then the nozzles on the VAZ need to be cleaned. However, before you start working, you must necessarily diagnose the car and only after that (if necessary) to clean. Why "if necessary"? The fact is that similar signs can be supplied not only by VAZ nozzles, but by a number of other units and components. Therefore, nothing ahead of time is not necessary.

Do I have to do this at a service station?

As for the diagnosis, of course, it must be carried out in the service center. But it is not necessary to clean the injectors of VAZ in the same place - this process can be done independently. If you give your iron friend a few hours of free time, you can save about 1.5 thousand rubles.

What changes after the nozzles are cleaned ?

VAZ in this case will get rid of all the problems that overtook him before repair. After this process, you will notice that the car began to consume less gasoline, the engine no longer stalls, the rpm does not jump, and the power will increase substantially. In winter, the engine start will be more harmonious, the speed of overclocking can also increase. It should also be remembered that the efficiency of cleaning directly depends on the degree of contamination - the more clumps on the nozzles were, the more problems with the operation of the gasoline engine will be eliminated at the outlet.
